Judy Sierra writes both childrens prose and poetry. Counting Crocodiles is
a prose picture book that seems fresh every time I read it. Regardless of how many times they have heard it before, my preschool
and kindergarten students enjoy the words and rhythm.

Extension: a) With younger children, introduce other poems
and songs that have to do with numbers, such as, This Old Man. b.) Point out the internal and end rhyme in the refrain (ten
crocs and so forth). Invite children to make up similar rhymes using other animals. For example, "One yak lying on his back.
Two yaks playing jacks."
